#battery capacity
- Ampere-hour — A unit of measurement for electric charge or the energy storage capacity of an accumulator or battery, represented by the symbol Ah. One ampere-hour corresponds to the total electric charge transferred by a steady current of one ampere flowing continuously for one hour, being mathematically equivalent to 3,600 coulombs.
- Ampere-hour — A compact graphical variant, less frequently used in modern technical texts, for the compound noun 'amper-oră'; a unit of measurement used to express the electrical charge capacity or energy reserves of a chemical accumulator or battery.
- Ampere-hour meter — An instrument or measuring apparatus designed to determine and integrate the total quantity of electricity flowing through an electrical circuit over a timeframe, expressed in ampere-hours (Ah). This device functions as a time-integrator of the electrical current intensity, being primarily utilized for monitoring the state of charge and discharge of industrial accumulator banks.
